I use my Cellphone to receive work alerts as part of my job. It is however, my personal cell phone. TAP is a service that allows a modem to send a text directly to verizon without internet connection. I use this to receive messages about network conditions such as network outages. On February 2, 2015 Verizon cancelled the service without warning. I contacted them about replacements they told me I could contact business sales or buy services from a third party. So now they want me to pay for services I used to receive for free.
